Abstract: 168,124. Jackson, W. J. Mellerah-, (Curless Co., Inc., W. A.). May 18, 1920. Tamping-machines; moulding pipes and tubes. -A machine for making, concrete pipes of the kind having a rotatable mould with a core is provided with means for removably engaging the core, both when in position in the mould and during removal, to hold it against rotation, means for controlling the rotation of various parts of the machine, and means for turning the tamping-bar to apply to a plurality of moulds in succession, and for adjusting the position of the tamping-bar with respect to the axis of the mould. The moulds 10 are supported on pallet plates 12 which are mounted on shafts 14 passing downward through the bed-plate 1 of the machine frame. A large gear 15 is mounted on the lower end of each shaft 14 and meshes with a pinion 8 loosely mounted on a vertical shaft 5, which forms the axis 9 of the main post 6 of the machine. The mould 10 is provided with an enlargement 16 a its upper end to form the bell end of the pipe. A central core 17 fits over a central pin on the pallet plate, and is held against rotation by a socket 21 slidably mounted on the end of an arm 22 pivotally mounted on the central post 6. The tamping-bar 43 slides in guide sockets 41 on anns 42 on a head 34, which can turn freely on the post 6. The bar 43 also passes through a friction clamp 44, which is connected to a crank pin on a disc 36 by a rod 45. The disc 39 is on a shaft 36 which is turned by bevel-gears 37, 32, the latter being mounted on a shaft 30 in the post 6. The position of the tamping-bar 43 may be adjusted by adjusting the sockets 41 in the arms 40, and it may be turned sideways by means of a hand-screw 49 on the side of the post 6. This screw 49 engages a lug 50 mounted on the head 34, whereby this head is prevented from turning. When the machine is equipped for working with two moulds alternately, the head is provided with two lugs 50. The shaft 30 forms an extension of the shaft 5 and is driven by means of clutch pieces 29, 31, Fig. 9. The clutch-piece 31 is mounted on the shaft 30 so as to slide into or out of engagement with the clutch-piece 29 on the shaft 5, and is operated by a lever 56 connected to the arm 57 of a. hand-lever 58. When the lever 58 is vertical, the two clutch-pieces 29, 31 engage. The shaft 5 is rotated by means of bevel-gears 3, 4, Fig. 1, from the main driving- shaft and carries a clutch 9, Fig. 9, which can be moved to engage with the pinion 8 by a lever 51. Depression of a pedal 52 disengages the clutch and it is held disengaged by a latch. When the lever 58 is pushed into vertical position to cause the tamping-machine to be. operated, the arm 57 withdraws the latch.

Patent GB-485337-A (GB)
Title: Time lag control device
IPC: G04F1/00
Filed: 1937-05-18
Abstract: 485,337. Time-lag control mechanisms. THOMAS, F. M. May 18, 1937, No. 13743. [Class 108 (iii)] A time-lag control device comprises a member formed of non-metallic material, e.g. thiokol resins prepared by the condensation of olefin halides with alkaline sulphides and heat-treated, the material having a large mechanical hysteresis characteristic so that under load the member moves slowly to a distorted shape and on release of load returns slowly to its original shape. In the device shown in Fig. 7, depression of a button b is adapted to engage the hooked end f of a rod e fixed to the button, with a spring-pressed lever k, a spring g surrounding the rod being simultaneously compressed between a flange on the rod and a plate h to which one end of the member i is secured, its other end being secured to a fixed panel a. The length of the member i thus increases under the action of the spring until a projection j on the plate h engages the lever k and rotates it clockwise to release the hook f whereupon the button b moves back to its normal position and the spring load on the member i is released. In order to measure the time taken for the mechanism to operate, an indicator may be attached to the plate h and protrude through a slot in a side panel to engage electrical contacts &c. In a modification, the member i is adapted to operate under compression or torsion. Fig. 9 shows a construction in which the member i is adapted to operate under flexure and in this case wear and changes in temperature are compensated for respectively by screwing the button b on the operating rod e and by the provision of a bimetallic strip p in the member i. The rate of return of the distorted member may be varied, e.g. by incorporating therewith a spring or damping material. A number of possible applications of the invention are mentioned. The Specification also contains some theoretical discussion illustrated by graphs.

Patent GB-143562-A (GB)
Title: Improvements in or relating to stop motions for spinning frames
IPC: D01H13/18
Filed: 1920-05-20
Abstract: 143,562. Pearson, G. W., (Assignee of Arragg, G. M.). May 7, 1919, [Convention date]. Stop-motions; delivery, stopping; thread-guides; rollers.-A stop-motion for spinning-frames comprises a member 0, Fig. 1, which, when an end breaks, is moved by an oscillating finger 51 about a vertical pivot so as to engage and release a flexible member 44, thereby allowing a weighted or spring-pressed pad 36 to lift the back top roller and grip the roving thereagainst, so that it is broken between the delivery rollers and the carrier rollers. The member 0 is praferably in two parts, which, though normally in alinement, are so pivoted that the tail part 10, Fig. 3, can pivot horizontally and vertically independently of the front part. The guide-eye in the member 0 is so formed that, in passing therethrough, the thread makes a double bend to prevent the member from chattering. The member 44 normally engages a shoulder 42 in a slotted plate 40, but is displaced therefrom into the slot by the tail 10, when an end breaks, so as to release the gripper-pad 36. When the member 44 moves from the projection, it turns a pivoted spring plate 90, Fig. 4, and releases it from a stop 91, whereupon it rises and restores the tail to its operative position, thereby enabling the end to be readily pieced. A carriage 71 is adapted so that, when it is drawn forward by the operative before piecing, it forces the spring plate away from the tail and under a stop 91, and replaces the member 44 behind the shoulder 42, thereby re-starting delivery. When the carriage is pushed back, the spring is retained beneath the stop until released upon breakage. A bar 8 is arranged to support the parts when stopping the frame. The top back roller is carried in a sliding hanger 20 loaded by an adjustable spring 24.

Title: Straight-bar knitting machine
IPC: D04B7/02
Filed: 1935-05-16
Abstract: 447,709. Knitting. ETABLISSEMENTS LEBOCY, 23, Avenue Pasteur, Troyes, Aube, France. May 16, 1935, No. 14313. Convention date, May 25, 1934. [Class 74 (ii)] In a straightbar knitting-machine for Basque bÚrets or the like, comprising a cylinder intermittently rotated and carrying strikers for actuating vary. ing numbers of needles, after forming a gore the cylinder disengages a pawl-and-ratchet device by abutment means and is returned to its initial position by a weight, whilst, after producing the required number of gores, the cylinder is maintained disengaged whilst finishing rows are being knitted. The cam carriage 6 is reciprocated by a roller carried on an endless chain and engaging a vertical slot 25 formed in a plate 26 rigid with the carriage. The carriage 6 drives either of two thread guide carriers 7, 8, by means of a dog 13 coacting with a downwardly curved finger 15 on the carrier 7 or 8. The fingers can be rocked upwardly against springs 18, and either of them may be so held by opposed wedges 5, 6, Fig. 5 (not shown), secured to the link 5, and thus one thread guide may be left at the end of its stroke and the other rendered operative. The needles are advanced by strikers 29 of various lengths arranged on a cylinder 27 pivoted on a shaft 35, and swung forward on arms 30 by a spring 34. As a cam 33 forces back the arms 30, a plate 39, journalled on shaft 35, abuts against a lever 58, and causes a pawl 37 to rack the cylinder round one tooth of a ratchet wheel 36. A pawl 38 acts as a stop in the forward swing of the cylinder. On the completion of a gore, an abutment 64 on the cylinder contacts with an abutment lever 60 and moves the lever 58 transversely from behind plate 39 which falls back, lifting pawls 37, 38, when a weight 51 restores cylinder 27 to its initial position. Meanwhile, lever 58 has moved opposite a second pawl-carrying plate 43, and racked the ratchet wheel 45 of a counting device one tooth, so that this ratchet counts the number of successive gores knitted. When the necessary number of gores has been knitted, a cam 47 carried by a disc 46 fixed to the ratchet wheel 45 acts to lock the lever 58 in this second position. At each alternate stroke of the levers 30 the ratchet 45 is now rocked one tooth until it has been moved as many teeth as it previously counted gores. Meanwhile, a second cam 48, carried by the disc 46, rocks a lever 53, and so, through the link 5, causes an exchange of thread guide carriers 7, 8. Finishing rows of the bÚret are now knitted until the disc 46 has been rotated through a sufficient angle to render cams 47, 48, inoperative, thus restoring the whole machine to its original setting.
Patent GB-915158-A (GB)
Title: Process for the preparation of aromatic polyether mixtures
Filed: 1961-04-20
Abstract: A process for the preparation of mixtures of aromatic polyethers comprises reacting an aromatic ether in the gaseous phase with a halogen e.g. chlorine or bromine to form a mixture containing aromatic polyethers and halogen-substituted products and subsequently converting all or substantially all the halogensubstituting products occurring in the reaction mixture by reaction with an alkali metal or an alkaline earth metal phenate or thiophenate, preferably at temperatures of 250 DEG -350 DEG C. and in the presence of copper, into aromatic polyethers.  The treatment with the phenate is preferably carried out in the presence of phenol corresponding to the phenate in order to keep the reaction mixture in the liquid state. Specified aromatic ethers are diphenyl ether, dinaphthyl ether, phenyl-naphthyl ether and diphenyl-phenyl ether which may or may not contain substituents such as halogen atoms.  Specified phenols are potassium phenate, sodium phenate, potassium cresolate, potassium naphtholate, potassium phenoxy-phenate, potassium para-phenoxy-phenate, potassium ortho-phenoxy-phenate, sodium meta-phenoxyphenate, potassium a -cumyl phenate, potassodium para-(para-tert-butylphenoxy) phenate, sodium para-Jpara-tert-butylphenoxy) phenate, potassium meta - phenoxy (para - tert - butyl phenate) and lithium meta-(meta-phenoxyphenoxy) phenate.  Thiophenates may be used in addition to phenates so that sulphur is introduced into the aromatic polyether molecule.  In an example streams of diphenyl oxide and chlorine, each containing nitrogen previously added, were led after being preheated separately to 450 DEG C. through a tubular reactor and the gas which emerges was cooled and separated into organic and aqueous layers.  29% of the diphenyl oxide converted was dehydrogenated and 71% substituted, the chlorine content of the product being 10.1% by weight.  The organic layer was diluted with carbon tetrachloride, washed with water and dried with Na2SO4 and the solvent was distilled off and the residue distilled under reduced pressure to remove and recover unconverted diphenyl oxide.  The residue is heated with a mixture of potassium phenate and phenol in the presence of copper powder and the mixture afterwards was washed with water and dilute caustic soda and dried with sodium sulphate to give a product having a chlorine content of less than 0.1% by weight.  The mixture of polyethers may be used as additives for lubricants and hydraulic fluids.  Specification 851,651 and U.S.A.  Specification 2,079,279 are referred to.
